DUPLICATING CHECK-BOOK.

SPECIFICATION forming part of Letters Patent No. 488,926, dated December27, 1892.

Application filed April 16,1892. Renewed December 2, 1892. Serial No.453,842. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH OLDFIELD, manufacturers agent, of the city ofToronto, in the county of York, in the Province of Ontario,Oanada, haveinvented certain new and useful Improvements in Duplicating Check-Books, of which the following is the specification.

My invention relates to improvements in duplicating check books and theobject of the invention is toprovide a simple means for attachingthecover to the book and it consists essentiallyin forming a slip in theupper part of the middle portion of the cover and attaching to thebottom of the stub a tongue preferably provided with sides beveled offin order that the tongue may be readily inserted in the slit, the coversbeing intended to be used in the manner hereinafter more particularlyexplained.

Figure 1,is a perspective view of the cover showing the slit. Fig. 2, isa perspective view of the back of the book showing the tongue. Fig. 3,is an enlarged sectional detail from the top to the bottom of the bookshowing the means whereby the book is held in position in the cover.

In the drawings like letters of reference indicate corresponding partsin each figure.

A, is the body of the book, 13, the cover which is made in one sheet andof three sections, 6, f, and, g. The section, 6, containing the blackleaf, the section, g, containing the tally sheet and the centersection,f, haviuga slit, f, (see Fig. 1). The back of the body of thebook has stitched to it a card board tongue, 0, which is preferablyattached when the book is being stitched or bound. The sides of thetongue, O, are beveled to the bottom edge of the tongue so as to enableit to be readily inserted in the slit, f, in the center portion,f, ofthe cover. It will be seen that this mode of attaching the cover is veryc0nvenient for this class of book to which it is intended to bedevoted-exclusively.

What I claim as my invention is.

A duplicating check book, consisting of a cover made up of threesections, with the black leaf on one side and the tally sheet on theother, leaving the back of the cover intermediate, a slit in the upperpart of this back section, and a body having a tongue secured thereto,and adapted to pass through the slit to the rear side of the back,substantially as described.

JOSEPH OLDFIELD.
